We performed a comparison between VMware SRM (Site Recovery Manager) and Zerto based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Zerto wins out in this competition. Its consistent sub-second response for RTO and RPO makes it one of the most responsive and fastest in the marketplace today. Users are able to easily run tests and change scenarios without any effect on an organization's production.
"The replication is the solution's most valuable feature. If we have some issues on the VM in the main site we can migrate it to another site automatically."
"VMware SRM is a very nice tool for disaster recovery for virtual environments."
"The UI is very user-friendly and testing is easy."
"The most valuable feature is the integration with our Nutanix environment."
"This SRM solution can improve your footprint within a data center."
"The solution is scalable."
"The product functionality is fairly high-quality."
"The installation and initial setup are straightforward."
"When we need to failover or move workloads, Zerto significantly decreases both the time it takes and the number of people involved. It only takes a single person to activate a failover and we can pretty much automate everything else."
"The ease of failover and test environments has proven invaluable."
"It is cost-effective and stable. It protects virtual machines, and there is a fast recovery time."
"The journaling is the most valuable aspect of the solution."
"The whole package is valuable. The most useful feature for the company is the rapid RTO, which offers a faster return to operations and brings us back online quicker. The last time we had an issue, we recovered within about 36 minutes, which was probably the most valuable thing for us because, previously, it took four to seven days."
"Zerto enables us to do sandboxing failovers. You can run tests on a production environment in a sandbox and spin up a copy of your actual production environment in a few hours. When you're done with it, you can click a couple of buttons, and it's all blown away. You don't need to worry about reverting changes or interfering with your on-prem production environments."
"The ease of use is one of the most valuable features when it comes to making changes and configuring. It's very easy to set up and configure. It's a great product."
"The most valuable feature for us is accelerating cloud adoption, as it helps provide greater speed for disaster recovery. Ultimately, this saves us time, as well as resources."
"There is room for improvement in the automation and orchestration aspects of this solution."
"Technical support needs improvement, they are not very responsive."
"You cannot use VMware SRM in conjunction with storage replication software."
"The solution is on the expensive side."
"We've had configuration issues on occasion. We start to fail over, and then we have to call it off because the configuration is not right, or the data stores aren't configured correctly in the secondary data center. Oftentimes, it is just the experience level of the team, and we have to bring in the vendor to help and validate our configuration."
"The price, in general, could be lower."
"Lacks stability and as a result requires continuous monitoring."
"The two vCenters have to be synchronized, which sometimes gives us problems because Keberos does not tolerate more than five minutes in time difference."
"I am a little bit worried about how Zerto will work with large volumes of data, such as replication for big data and very large files."
"Analytics has a 90-day window, where it keeps data. It would be nice to have on-prem storage instead of cloud storage for that so we can keep the data for longer. Unless you discover the problem within three months, you don't know that you need the data. Then, it is gone by the time you realize there is an issue."
"They are not cheap. They are more expensive than others."
"When building out a VPG and doing the machine types within Azure, they were not coming across correctly. It would say it had a CPU and memory of a specific type, but it was not accurate... It was a bug and they were working on it."
"Zerto is too reliant on VMware's vCenter. It's tough to upgrade, move, or do anything related to virtual servers with vCenter."
"Zerto's near-synchronous replication is excellent when it works. I'm trying to be nice to them because I like the product a lot, but we're having a lot of difficulty with it in our environment."
"Customer service and technical support need improvement."
"Overall, Zerto is doing a very good job. We have experienced a few downtimes on networking. Most of the time, they come up with a solution immediately to sort out any challenge that may affect data flow or data migration. It does not happen frequently. We might experience it once in two months, but when we face any downtime, it does not impact the data."
